AD 2007-13-16

(a) This airworthiness directive (AD) becomes effective August 10, 2007.

(b) None.

(c) This AD applies to Model DA 42 airplanes, serial numbers (S/N) 42.004 and up, certificated in any category.

(d) Air Transport Association of America (ATA) Code 57: Wings.

(e) The mandatory continuing airworthiness information (MCAI) states:

It has been determined that the surface roughness of the wing stub safety walks Series 300, gray color (equals sandpaper grid 40), installed during production on some aeroplane S/Ns, adversely affects the aircraft single engine climb performance.

AFM published twin engine climb performance is not affected by this AD.

(f) Unless already done, do the following actions:

(1) For S/N 42.004 through 42.035, and 42.037: Within 60 days after August 10, 2007 (the effective date of this AD), do the following actions following Diamond Aircraft Industries GmbH Mandatory Service Bulletin No. MSB-42-006/1, dated September 20, 2005:

(i) Exchange the wing stub safety walks following paragraph 1.8, Action 2 a) to b) of Diamond Aircraft Industries GmbH Mandatory Service Bulletin No. MSB-42-006/1, dated September 20, 2005.

(ii) Insert Diamond Aircraft Airplane Flight Manual Temporary Revision Performance Data DA 42 AFM TR-MÄM-42-111/a, dated September 20, 2005, Revision 3 to the Airplane Flight Manual (AFM), or any future revision that incorporates the same information into the Diamond Aircraft Industries GmbH Aircraft Airplane Flight Manual DA 42, Doc. 7.01.05-E.

(2) For S/N 42.036, 42.038 through 42.064, 42.107, 42.109, 42.110, and 42.177: Within 60 days after August 10, 2007 (the effective date of this AD), insert Diamond Aircraft Airplane Flight Manual Temporary Revision Performance Data DA 42 AFM TR-MÄM-42-111/a, dated September 20, 2005, Revision 3 to the AFM, or any future revision that incorporates the same information into the Diamond Aircraft Industries GmbH Aircraft Airplane Flight Manual DA 42, Doc. 7.01.05-E.

(3) For S/N 42.004 and up: Within 60 days after August 10, 2007 (the effective date of this AD), adhere to the following:

(i) No wing stub safety walks Series 300 (equals sandpaper grid 40), gray color, part number (P/N) D60-1127-10-51 (no revision letter attached) may be installed as a spare part on the Model DA 42 airplane. Only Diamond Aircraft Industries (DAI) GmbH released safety walk P/Ns with a surface roughness equal to or finer than sandpaper grid 100 are approved for installation as spare parts.

(ii) Diamond Aircraft Airplane Flight Manual Temporary Revision Performance Data DA 42 AFM TR-MÄM-42-111/a, dated September 20, 2005, Revision 3 to the AFM, or any future revision that incorporates the same information, must remain part of Diamond Aircraft Industries GmbH Aircraft Airplane Flight Manual DA 42, Doc. 7.01.05-E.

Note:

This AD differs from the MCAI and/or service information as follows:

(1) The MCAI and service bulletin require the insertion of Diamond Aircraft Airplane Flight Manual Temporary Revision Performance Data DA 42 AFM TR-MÄM-42-111/a, dated September 20, 2005, Revision 3 to the Airplane Flight Manual, or any future revision that incorporates the same information into the Diamond Aircraft Industries GmbH Aircraft Airplane Flight Manual DA 42, Doc. 7.01.05-E, immediately upon receipt. We consider immediately upon receipt as an urgent safety of flight compliance time, and we do not consider this unsafe condition to be an urgent safety of flight condition. Because we do not consider this unsafe condition to be an urgent safety of flight condition, we issued this action through the normal notice of proposed rulemaking (NPRM) AD process followed by this final rule. The time of 60 days after August 10, 2007 (the effective date of this AD) is an adequate compliance for this AD action and met the FAA requirements of an NPRM followed by a final rule.

(2) Paragraphs A)i) and B)i) of the MCAI, state to assure that AFM TR-MAM-42-103, distributed with DAI MSB42-005, is inserted into AFM Doc. 7.01.05-E, rev. 2 or earlier revision. This AFM requirement was for an MCAI on which the United States did not take AD action. The action is no longer necessary when the actions in this AD are done. Therefore, the action is not being mandated in the U.S. AD action.

(3) The MCAI references revision 2 of the AFM. The FAA AD references revision 3.

(g) The following provisions also apply to this AD:

(1) Alternative Methods of Compliance (AMOCs): The Manager, Standards Staff, FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19. Send information to ATTN: Sarjapur Nagarajan, Aerospace Engineer, FAA, Small Airplane Directorate, 901 Locust, Room 301, Kansas City, Missouri 64106; telephone: (816) 329-4145; fax: (816) 329-4090. Before using any approved AMOC on any airplane to which the AMOC applies, notify your appropriate principal inspector (PI) in the FAA Flight Standards District Office (FSDO), or lacking a PI, your local FSDO.

(2) Airworthy Product: For any requirement in this AD to obtain corrective actions from a manufacturer or other source, use these actions if they are FAA-approved. Corrective actions are considered FAA-approved if they are approved by the State of Design Authority (or their delegated agent). You are required to assure the product is airworthy before it is returned to service.

(3) Reporting Requirements: For any reporting requirement in this AD, under the provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et.seq.), the Office of Management and Budget (OMB) has approved the information collection requirements and has assigned OMB Control Number 2120-0056.

(h) Refer to MCAI Austrian Civil Aviation Administration Austro Control GmbH AD No. A-2005-003, dated October 21, 2005; Diamond Aircraft Industries GmbH Mandatory Service Bulletin No. MSB-42-006/1, dated September 20, 2005; and Diamond Aircraft Temporary Revision Performance Data DA 42 AFM TR-MÄM-42-111/a, dated September 20, 2005, for related information.

(i) You must use Diamond Aircraft Industries GmbH Mandatory Service Bulletin No. MSB-42-006/1, dated September 20, 2005; and Diamond Aircraft Temporary Revision Performance Data DA 42 AFM TR-MÄM-42-111/a, dated September 20, 2005, to do the actions required by this AD, unless the AD specifies otherwise.

(1) The Director of the Federal Register approved the incorporation by reference of this service information under 5 U.S.C. 552(a) and 1 CFR part 51.
